Just thought I would add my two cents worth. In Darwin Gross' book
"Your Right To Know"(copyright 1979) there are four ink line drawings
of Eck masters: Fubbi Quantz, Gopal Das, Lai Tsi, and Rebazar Tarzs
[sic]. They pretty much look the way they "should" look. I would say
the quality of the drawings is very high. On page ii it states "Ink
sketches by Helen Baird." I don't know whether these predate Diane
Stanleys artwork or not.
